Fin whales are the 2nd largest animal on earth, which limits options for moving or freeing stranded animals.

According to NOAA Fisheries, large whales may strand alive for a number of reasons, including the following.

  • complex topographic and oceanographic conditions
  • contaminants
  • weather conditions
  • natural toxins such as domoic acid or saxitoxin poisoning
  • disease, emaciation or malnourishment
  • human-caused injuries

The NOAA West Coast Marine Mammal Stranding Network was established in the early 1990s under the Marine Mammal Protection Act. Members of the network respond to marine mammal stranding events along the California, Oregon, and Washington coasts and are part of a nationwide network. The Network responds to all large whale cases to better understand what factors may have contributed to the stranding.
